Ok so I just started using this. It runs about a gajillion times faster on my computer than Lightroom did. In any case, the only complaint I have so far is that I open my RAW files no problem. Then I go and click "Open Image" after making small adjustments. Then I'll crop it and play around a little in the program. Then I do Save As and no matter if it's TIFF or JPEG I lose all the exif data. It puts in that it was created in CS3 and that it was taken with a D80, but I'd like to retain my aperature, shutter speed, flash, iso, etc.

Couldn't replicate it myself. Don't see a setting for it in ACR or PS preferences. The only thing I know of that strips the exif is the "save for web" feature (you can enable it though), but since it happens with tiffs you are obviously not using that.

Might be worth a preferences reset:

Ctrl-Alt-Shift in Windows (Command-Option-Shift in the Mac) while starting up Photoshop ... dialog box will pop up asking to delete the settings file.
